Rab5 is a g.Pase protein that is involved in intracellular membrane trafficking. It functions by binding.to various effector proteins and reg.lating.cellular responses, including.the formation of transport vesicles and their fusion with the cellular membrane. Rab5 has been reported to play an important role in the development of the zebrafish embryo;however, its role in axonal reg.neration in the central nervous system remains unclear. In this study, we established a zebrafish Mauthner cell model of axonal injury using.sing.e-cell electroporation and two-photon axotomy techniques. We found that overexpression of Rab5 in sing.e Mauthner cells promoted marked axonal reg.neration and increased the number of intra-axonal transport vesicles. In contrast, treatment of zebrafish larvae with the Rab kinase inhibitor CID-1067700markedly inhibited axonal reg.neration in Mauthner cells. We also found that Rab5 activated phosphatidylinositol 3-kinase(PI3K) during.axonal repair of Mauthner cells and promoted the recovery of zebrafish locomotor function. Additionally, rapamycin, an inhibitor of the mechanistic targ.t of rapamycin downstream of PI3K, markedly hindered axonal reg.neration. These finding. sug.est that Rab5 promotes the axonal reg.neration of injured zebrafish Mauthner cells by activating.the PI3K sig.aling.pathway.
